.T0 all whom it 'may concern.'

' Be it known that we, .PHILIP JOHN Wens- LEY, a director of the United Alkali'Com-4 .pany, Limited, WILLIAM WINDUS, manager, 5- and BENJAMIN BRACEY, foreman, subjects'of the Queen-'of Great Britain and Ireland, and .t all of Net m'Chemical Works, Bristol`,rEng land, 'havetvrnvented certain Improvementsin or Connected with Pumping and Absorbing 'zo Chlorin'Gas and Apparatus for Use Therein,

of which the following is a specification.'

Chlorin gas, particularly when diluted with `airol other inert gases, such 'as is obtained 4 by the Deacon process, or other similar pro- ;:5' cesses, is diliicnltI to absorb in milk of lime, or other solutions.

from the corrosive action of chlorin gas, which renders the use of ordinary metallic pumps and pipes almost impossible, and nee, use of very extensive surfaces ofthe absorbing liquid. The 'ally employed'is moreover liable to frequent By our invention milkof lime, or other solution, whereby we obtain complete absorption. in tively smalt apparatus. We passi the chlorin gas, 3o source it may be derived, through, or over, a hygroscopic substance exposinga large surface; for instance, coke moistened with sulfuric acid. By this means we obtain the chlo f rin gas ina dry condition, in ,which we find it 35 does not act readily on ordinary metals, and can be pumped by means of an ordinary air compressor. :We can use an ordinary pump to force the dry chlorin gas through passages, Y. or pipes, which may be metallic pipes under 4o the surface of the absorbing fluid, and at any suitable dept-h below the surface connect to them a distributor, which causes the chlorin gasto pass in ine'streamsprbubbles, through the liquid. -As drying apparatus we may employ a lead chamber or tower, or an earthenware vessel lled with pieces of -coke or the like over which a steady stream of strong snlfuric acid is kept iiowing. The moist gas enters at the bottom and an outlet pipeh at The difliculty arises chiey.

The .inlet and outlet valves may also be made of metal. Or the pump cylinder and pistonmay be lined with ebonite or the like materials and tliegvalves may be india rubber valves. We nd itadvantageous tolubrcate the com pressoir. freely with a pure mineral oil, which, besides its use as a lubricant, protects -the metallicparts againstV any slight action the chlorin may" The oil m'ust be ofv such quality that the dry gas to the it is'uotacted upon by chlorin gas. The

pipes or passages conveying the gas fiiom the drying apparatus to the pump and from the pump to theabsorbing apparatus may be The distributor consists of a system 'of pipes or passages having slots or the like on the undersidey which slots prevent thevaccumnlationl of solid matter and consequent" choking of the distributer. The gas issues purposes.

Figure 1 of the accompanying drawings resents an arrangement of apparatus suitable and its adj uncts.

Tiiechlorin gas enters by thepipe A into the drying apparatus consisting ofi/a vessel in which coke is supported, the said vcoke 9o being moistened by sulfuric' acid supplied by the hooded pipes c eading from the receptacle C for the acid, and the moisture removed from the gas leaving by the liquid seal outlet at c. The dried gas then passes by the'pipe 95 D to the pump E which is shown as a hori-1 I zontal double acting pump but it maybe a pump or forcing device of any convenient kind. The gas is forced by the pump throughV the pipe F into the vessel G containing the absorbing liquid the pipe F having distributing branchesfperfornted on their under sides bles directed downward and then it passes npward through the liquid.-

g is the outlet from the vessel G and Il is a stirrer situated beneath the pipe F and u branches f.

Having now particularly described andasoertained the nature of our said invention and in what manner the same is to be performed, we declare that what weA claim is 1. The method of absorbing chlorin gas consisting in dehydrnting the gas and pump- Zing the dry product into Vessels containing the absorbing liquid, substantially as described.

2. In an apparatus for absorbing chiorin zo ges, the,oombination with n debydrater, of a. pump, and an absorbing vessel through which the gas successivelypnsses. 'and n distributor "in 'seid absorbing vessel having slts or small openings on the under side thereof, snbstan 'z5 tially as described.
